What finish you put on old burnt wood?

To enhance old burnt wood, consider using a clear epoxy finish, which can seal and protect the surface while showcasing the unique texture and color of the wood. Alternatively, a penetrating oil, such as Danish oil or tung oil, can nourish the wood and provide a subtle sheen without obscuring the natural beauty. For a more polished look, a polyurethane finish can be applied, providing durability and moisture resistance. Always ensure the wood is clean and properly prepared before applying any finish.
